Absolutely synthetic oil is better quality...the question is do you need it. Nobody would argue that washing your car with bottled water would be better cause it is more pure, but would it really make a difference in how your car would look compared to garden hose water (ok, not if it is real minerally). You can easily get 250K on an engine with dino oil, so how many people actually get that? very few cause lots of other things go wrong and people want newer cars by that point (majority).

You don't have to do any "flush" with switching between these oils. Stick with dino and regular 3K oil changes, or go synth and spend more money...either way if you are regular you will be fine. Dino oils have come a long way in their processing. No argument that synth is better than dino...but this isn't a space shuttle.
